Calcium carbide residue Presently days a tremendous issuerelatedinthefieldofdevelopment&Constructionisthe utilizationofnaturalresourcesontheourplanet,around40 % natural resources fulfilled the demand in construction field.Thenagainthecementindustriesdeliveredalotofnon rottingwastematerials.Suchsortofmaterialsstays inthe climate for many years and having a principle issue of arranged.Transparentlyunloadingofsuchkindofmaterials addingtotheclimateissue.Calciumcarbideresidue(CCR)is anacetylenegas(C2H2)byproduct.
Ground granulated blast furnace slag GGBS is acquired viaquenchingmoltenironslagfromablastfurnaceinwater, tosupplya glassy,granularproductthisisthendriedand convert into a fine powder. GGBFS is used to make long lasting concrete structures in combination with normal Portlandcementorotherpozzolanicmaterials.GGBFSreacts likePortlandcementwhilstintouchwithwater.

The basis of the present study is to use of cement supplementsandsteelfibersintoconventionalconcrete. The grade of concrete used as M 40 and the cement considerasOPC,OrdinaryPortlandCement.TheCement supplement used GGBFS Ground Granulated Blast Furnace Slag as 30% and 40% by weight of Cement. Similarly the samples will be prepared with 30% and 40% GGBFS along with additional 5% calcium carbide residue. The beam samples for the following study is castedtoevaluatetheflexuralstrength.Forstudyingthe effectoffiber,concretemixesthesteelfibrecontentequal to1.0%bemade.Beamspecimensofsize100mm*100 mmand500mmwithdifferentfibrousconcretedepth 25, 50, 75 and 100 mm from the bottom were investigated.
1.1 MATERIALS USED IN RESEARCH
Monika Bala Verma1 & Ms Shweta Chouhan2
The
Steel fiber reinforced concrete (SFRC) is a composite material whose parts incorporate the conventional constituentsofPortlandcementconcreteandascatteringof arbitrarily situated short discrete steel fibers. Similarly as withallFRCmaterials,contrastedwithplainconcrete.
Abstract Lately, a few examinations and researches were accounted on GGBFS independently. The study revealed in the report presents experimental work on the strength parameters of GGBFS along with the Calcium Carbide Residue in concrete. The grade of concrete that modified by using this combination is M 40. Here GGBFS used as a partial replacement of cement (30% and 40% by weight of Cement replacement) and Calcium Carbide Residue as additional cement replacing material with GGBFS. The amount of CCR that used in present work is limited to 5% only by cement replacing material. Present work is dealing with compressive as well as flexural strength of mixes. To enhance the flexural strength of the mix 1% Steel fibers also used with depth variation of beam. Depth variation considering as 0.25d, 0.5d, 0.75d and full depth of beam d. The curing period consider in present study for concrete were 28 days and 56 days for compressive strength and 56 days for flexural strength.
